Hi,
We are looking at a pilot project to test an Oracle database running on
Linux/zVM. Currently we have about five applications that run on various
HP Unix servers. Each of these applications connect to their own Oracle
instance. Each instance is about 300GB, so we have 1.5TB for the

There's no real good way except for actually testing a representative
workload.
The Project people are also worried that the VM overhead will result in
slow response times. We
IBM offers some comparison engines for this type of workload when moving to a
z/series. The more (accurate) data you can
get from the HP Unix servers the closer IBM CPU and memory requirement will be to
reality. IBM I'm sure would be glad to help.
Don't think CP overhead will be a limiting
Ken, IBM has a couple of modleing tools available to size the workload on
zLinux and IFLs/Memory. If you have a locak IBM rep or business partner rep
You may want to ask about the Size390 or New Workload sizing that IBM

Well, you've come to the right place :)
We've just migrated our HP-UX Oracle server to Linux on zSeries. We had an
N-4000 with two CPU's (440mhz) PA-RISC 8500. It was far overloaded. It is
currently using about 95% of one IFL.

Ken,
Richard is on the right track here. Short of a Size390 sizing I can tell
you that the range of relative capacity between a z900 is quite broad. The
actual result will depend on what kind of workload is being done (query
only, some updates, heavy transactional), the cache working set
